GB/T 43763-2024 "Aerospace Functional Plating Coatings, Special Non-metallic Material Metal Platings" specifies the technical requirements, test methods, inspection rules, identification, accompanying documents, Encasement, transportation and storage conditions for functional metal platings on the surface of special Non-metallic materials such as polyether ether ketone (PEEK), polyphenylene sulfide (PPS), polyimide (PI), liquid crystal polymer (LCP) and their composites. This standard applies to metal platings on the surface of special Non-metallic materials in aerospace applications, such as nickel-gold, nickel-silver, copper + nickel + gold, copper + nickel + silver, pure nickel, etc., to achieve conductive and welding functions. The standard also refers to the relevant coating thickness measurement, adhesion strength evaluation, brazing inspection and other standard methods to ensure that the platings mass and performance meet the requirements.
